The microscopic mean-field model, which describes nuclei with the degrees of freedom of nucleon, is one of the effective approaches to prepare the nuclear data for unknown nuclear fission.
Although the recent microscopic mean-field model uses the effective interaction based on the energy density functional theory, the interaction for the fission is not prepared, and the important factors to describe the fission are also not clear.
Therefore, we investigate the fission path by using the microscopic mean-field model with the effective interaction
employed in nuclear physics.
The fissioning path on U-236 with respect to the nuclear elongation and mass asymmetry is investigated by the constraint mean-field model represented in the three-dimensional coordinate.
In this talk, we will analyze the potential energy surface for the fissioning path to separate into seven energy components and report their behaviors.
